Provided are a metal PCB, a headlight module having the metal PCB applied thereto, and a method for assembling the headlight module, wherein the metal PCB has a base made of a metal material and configured as a thin plate, or the base has a predetermined thickness and is bent in a desired direction through a bending groove formed on the rear surface thereof, and the base has a plurality of chip mounting portions integrated thereon such that one or more LED chips are mounted thereon, the chip mounting portions being spaced at a predetermined interval and having at least two parts of incision surfaces formed on one side of the base such that the chip mounting portions are inclined and installed to have a predetermined angle with regard to the base.

An electrical connection between the backplane and the light-transmissive front electrode of an electrowetting device is provided by forming an aperture through the top front electrode coupled and a substrate coupled thereto and subsequently introducing a flowable, electrically-conductive material into the aperture. The flowable, electrically-conductive material provides an electrical contact between the light-transmissive electrically-conductive layer and the backplane.

The joint portion is more brittle than the via conductor. A linear expansion coefficient of the second resin layer is larger than a linear expansion coefficient of the via conductor and a linear expansion coefficient of the joint portion, and is smaller than a linear expansion coefficient of the first resin layer.

Lighting panels and methods of manufacturing lighting panels are described. An example lighting panel includes a substrate that has a planar surface, electrically conductive traces printed onto the planar surface of the substrate, and light sources mounted onto the electrically conductive traces at mounting positions such that the electrically conductive traces form an electrical interconnection between selected ones of the electrically conductive traces and associated ones of the light sources.

A method of producing a functional vehicle component includes fixing a leather sheet over a surface of a vehicle component, applying a flexible electronic circuit to an A-surface of the leather sheet, and arranging a pigmented coating over the circuit. The pigmented coating inhibits or prevents the circuit from being visible through the pigmented coating. The method may include attaching an electronic element, such as a light source, a sensor, a wireless transmitter, or a switch, to the circuit. When the circuit includes a light source, the pigmented coating inhibits or prevents the light source from being visible through the pigmented coating, but light emitted by the light source is visible through the pigmented coating.
